✅ CHINT 185486 – G EBC 4P C25 3kA Description The CHINT G EBC 4P C25 3kA miniature circuit breaker (MCB) delivers enhanced four-pole protection for balanced three-phase + neutral loads. With a 25A rating and C-curve tripping characteristic, it is ideal for safeguarding commercial lighting systems, air handling units, and industrial power distribution boards where neutral disconnection is a safety requirement. This MCB supports a 3kA short-circuit breaking capacity and complies with IEC 60898 standards. The device ensures full-phase and neutral isolation during fault conditions, and its DIN rail mount and screw clamp terminals enable fast, reliable installation in low-voltage switchboards and control panels.
